Squeaky Clean Reads is a website specializing in content reviews of books for middle grade (10-14) and teen (14-19) readers. An excellent resource to help the reader (or parent!) find "clean" books.
Regarding their reviews, Squeaky Clean Reads says:
"In our review process, we give an overall review (a review of the book's literary qualities), and then a content review (a discussion of possibly objectionable material found in the book). We want to let our readers know that our overall reviews and ratings are NOT affected or influenced by the book's content. We aim to provide a professional, literary review of each book, and then go on to simply provide the book's content for your consideration."
Books are separated into lists organized by star rating, age level, topics (fiction, non-fiction, paranormal, mystery, etc), and the ones that make the cut are put on their Squeaky Clean Book List.
